NEW YORK (CBSNewYork/AP) – A financial services company and a technology firm have signed five-year leases at New York City’s One World Trade Center.

The Durst Organization and the Port Authority of New York and New Jersey announced Tuesday that Tinypass and Casablanca Capital LLC will move into the 1,776-foot skyscraper.

Tinypass creates e-commerce software that helps online publishers sell their content through paywalls or other means. It has leased 4,936 square feet on the 46th floor of the tower.

Casablanca Capital is an investment advisory firm that pursues activist strategies. The firm has leased 2,488 square feet, also on the 46th floor.

One World Trade was previously known as the Freedom Tower. The 1,776-foot tower is the tallest building in the United States.

Anchor tenant Conde Nast occupies 1.2 million square feet with its 25-year lease.

The eight-year construction of the skyscraper came after years of political, financial and legal infighting that threatened to derail the project.

The bickering slowly died down as two other towers started going up on the southeast end of the site: the now completed 4 World Trade Center whose anchor tenant is the Port Authority, and 3 World Trade Center that’s slowly rising.

T.J. Gottesdiener of the Skidmore, Owings & Merrill architecture firm told The Associated Press in November 2014 that the high-rise was built with steel-reinforced concrete that makes it as terror attack-proof as possible.

He said the firm went beyond the city’s existing building codes to achieve that.
